To all whom it may concern: v

Be it known that I, Cnarsrornnn 0. Do- LAN, a citizen of the UnitedStates of America, residing at Lockport, inthe'county of Ni agara andState'of New York, have invented new and useful. Improvements inHoisting and ConveyingMechanisms, of which the following is aspecification.

This invention relates to hoisting and con veying mechanisms designedespecially for use as a" clam or other dredger, and has for its objectsto produce a comparatively simple inexpensive device of this characterin which the load may be, readily collected,hoisted, and conveyed fromlace to place, one Wherein the carriage wil travel smoothly during theconveying operation, and one in which the load will upon reaching itspoint of destination be automatically released and deposited. v

A further object of the invention is to provide a device of thischaracter inwhich the carriage-o crating cable serves as a guide uponwhic the carriage travels, one wherein the sections of the conveer-bucket will be automatically locked in c osed osition, one whereinthe locking member wil be automatically released through the action ofthe hoisting-cable, and onein which the movable head included in theload-carrying device will be guided in its movements and cushioned atthe completion of, the latter;

With these and other objects in view the invention comprises the novelfeatures of construction and combination of parts more fully hereinafterdescribed.

. In the accompanying drawings, Figure 1 is a side elevation of ahoisting and conveying mechanis embodying the mvention. Fig. 2 is anenlarged side elevation of the load-receiving device and carriage. Fig.3 is an enlarged detail view, partly in section, of parts of the loadreceiving and conveying device. Fig. 4 is an end elevation, on anenlarged scale, of the load receiving and conveying device and showingthe bucket in closed position.

Fi 13 is adetail end view showing a modified Topling device. Fig. l iis a detail side elevation of one-of the grapplingmembers.

Referring to the drawings, 1 and 2 designate a pair of supports,preferably in the form of osts or standards, arranged in spaced re ationat points between which the load is to be conveyed, said standards beingbraced by guy-ropes 3 and having extended therebetween a horizontalguide element or cable 1, attached in any appropriate manner vertical tothe upper ends of the standards and constituting a track or way on whicha carriage 5 is arranged for travel.

Arranged adjacent to the standard 1' is a' frame 6, having.jou-rnaled'for rotation there in ahoisting-drum 7 and a carriage-ocrating drum 8, connected for rotation one fi orn. the other by means ofintermeshing gears 9 and 10, ofwhich the latter is fixed upon apowershaft 1 1, dis osed in axial alinement with the shaft 12 of thegear 10 or its shaft a fixed clutch member rum 8, there being providedon rm of load-grap- 13, adapted for engagement by a companion clutchmember or adjacent end of the shaft 12, but keye to and for rotationwith the latter. The clutchhead 14 is adapted for movement to engagingor non-engaging position by means of-an op crating-lever 15, pivoted atits inner end to a collar lo'uponthe clu-tch-head and between its endsto the frame, there being attached to the latter a toothed ratchet 17,adapted for engagement by a pawl 18, carried by and for locking thelever in its adjusted position.

The drum 8 is com os'ed of a pair ofportions or sections 19 an 20,havingtheir meeting ends provided with outstanding marginal flanges 21, havinga series of spaced perfora tions 22, any one of which may receive asingle fastening member or bolt 23, adapted for normally connecting thedrum-sections for slmultaneous movement, the sectionilg being positivelyfixed to and for rotation with t e shaft 12 by means of a spline orfeather 24, whilethe section 20 is idly mounted u on the shaft for apurpose which will hereinafter appear. The shaft 12 may be designed forengagement with a ratchetead l4, slidable u on the roo ' for travelaround apair of guide-pulleys on the post 1 and extended thence around aguide-pulley 31 at the upper end of est 2, 1o

arranged for travel upon that portion of the ends with journals 42, oneach of which is at their lower ends in a slotor-reoess 49, pro- 51,pivotedv int e 'at 32, to the carriage 5, which'latter is,

wheel 26, fixed on the shaft, the shaft of l drum7 being similarly fixedagainst m'ovement by a pawl 27 and. ratchet 28. i

Attached at one end to the section 20 of drum 8 to be wound thereon is aflexible carriage-operating element or cable 29, arranged i the otherend of said cable being attac ed, as

equipped witha pair of-wheels or rollers 33,

cable 29 which extends between the standards and with a second pair ofwheels 34, designed to travel on the track or way 4, there being engagedwith the section 19 of druTm S and to be wound thereon a secondcarriageoperatin element or cable 35, led around guide-pu leys 36011 thepost 1 and engaged at its other end, as at 37, to the carriage. It is tobe noted in this connection that the cables 29 and 35 are attached to bewound in relatively reverse directions upon the druin 8, whereby as onecable is wound the other will be paid out, thus to positivel move thecarriage back and forth upon t e track 4, and, further, that the cable29 serves not only for moving thecarriage, but also'as a guide for thelatter in its movements.

Connected to and for engagement with the carriage 5 in a mannerhereinafter explained is a load-receiving device 38, in which 39designates a sliding head or block arranged for travel upon apair ofverticalguide elements or rods 40, fixed at their lower ends to a hori-Y zontal cross piece or bar 41, provided at its pivoted a pair ofcrossed members or levers 43, fixed at their lower ends to the sections44 of a load-receiving bucket or scoop 45, the levers 43 being pivotedat their upper ends to connecting members or links 46, in turn pivotedtoa cross piece or bar 47, .c arrying a pair of vertical guides 48,adapted to bear upon the inner edges of the guide 40 and fixed vided inthe bar, there being also fixed in said recess a centrally-dispcsed-pinor keeper 50,

designed for en agement by a movable latch block 39 and serving todetachably connect thelatter and bar. The up- I per free end of thelatch 51 is disposed between a pair of pressure members or plungers 52,ar-

ranged in a suitable 0 ening or recess in the head and acted uponypressure-springs53 to maintain the latch 1n centered enga ing position,there being provided upon the p unge'r-heads outwardlyextending bearingportions or fingers 54, is osed in uide o enlngs or slots 55 in the sideaces of t e hea 39 for guiding the plungers in their movements, the

upper ends of the guide members 48 being sharpened, as'at 56, for readyentrance into the block 39.

' ley 61 on the carriage and latch 51 in the manner and which will bemore fully described hereineach spring a terminal Connected with thedrum- 7 to be wound thereon is ahoisting element or cable 57, extendedaround guide-pulle s58 on the post 1, from which it is led around apulley 59 on the carriage, thence over a pulley 60, journaled in thehead-block 39, then up and over a pulhaving its terminal fixedlyattached, as at 62, to the block, it being apparent that when the cableis wound upon t will be'hoisted toa positionbeneath the-carriage 5 andfor:movement with the latter in its travel upon the guides 4 and 29.Connected in the cable 57 is a short chain-section 63, to one link ofwhich there is fixed a latch-operating member or block 64, designedtocontact with the u per end of the ibrthe purpose after.

Provided on the side faces of the block 39- 1s a pair of oppositel ingcars 65, to each 0 66, in turn pivoted, as at 67, to the upper end of asecond link 68, the lower end of which is pivoted to an car 69, fixed tothe upper outer edge of one of the bucketsections 44, while carried bythe links is an engaging member orarm 70, having offset engagingportions or fingers 71 designed for engagement with the links to limitthe inward movement of the latter at the pivot 67. It is to beunderstood in this connection that there are two sets 01' pairs of links67 68, each of which connects one of the bucket sections with the head39, whereby the latter will serve, through the medium of the links, formoving said section to open-or closed position.

Disposed upon the lower ends 40 are buffer-sprin s 72, adapted toreceive the bar 47 for cus 'onin the parts of the mechanism when the bucet-sections are in open position, as illustrated in Fig. 6, while uponthe upper ends of the uide there are fixed buffer-springs 73 to receiveand cushion the block 39 when the parts are in dumping disposed andprojectof the guides position, as illustrated in Fig. 5. The springs 73areconnected with their respective guides, preferably by forming on theupper end of loop or coil 74, engaged around a threaded neck 75, formedon the guide and clamped between a pair of lates or washers 76, in turnsecured in place y a nut 77, there being formed, in the lower washer amarginal recess 78, through which the upper coil of the spring is passedto engaging position.

In practice the drum 7 is operated from the shaft .11 throu h the mediumof the gears 9 and 10 for win ing or unwinding the cable 57 to raise andlower the device 38, the clutchhead 14 being normally shifted tonon-engaging position, as illustrated throwing the drum 8 out of action,under e di'um the-load-carrying device 38 in Fig. 1, -forwhich ispivoted a link pivoting axle 67 of the pair of which conditions saiddrum isfixedagainst eiaaea movement by means of the pawl 25 engaging theratchet 26. After the bucket 45 has received a load and been hoisted tothe position v illustrated in Figs. 2 and 4 for movement with thecarr'ia e 5 the pawl 25 is released and the clutchead 14 shifted toengaging position through the whereu on the drum 8 will be operated fromthe sha 't 11 for winding one of the cables 29 or and unwinding theother, thus causing the carriage to travel along the way 4 to the pointat which the load is to be deposited, whereupon the drum 7 is a ainthrown into action for further winding the cable 57 until the member orblock 64 contactswith the end of latch 51, whereupon the bar 4'? will bereleased and slide downward on the guides to the position illustrated inFig. 5, thus acting, through the medium of the links 46 and levers 43,to move the bucket-sections 44 to open or dischargingposition. Withthebucket-sections in this position the device is again moved, throughthemedium of the carriage 5, to the point for receiving another load,and the drum 7 is rotated in the proper direction for unwinding cable 57whereu on the device 38 will descend until the bud etsections still inopen position rest upon the ground, whereuponthe head 39'will continueto descend until the latch 51 engages the keeper and the parts'assumethe'position illustrated in Fig. 6. When the cable 57 is again wound,the head 39 will first move up-' ward upon the guide and act, throughthe medium of the links, for moving the bucket-sec tions to closedposition and at the same time for automatically receiving a second load,the previously-described operation being then repeated for conveying theload to and discharging it at the point where it isto be de-" posited.It is to be noted that when the bar 47 is released and descends it willbe received u on and cushioned by the springs 72, while t e block39 willin like manner be cushioned by springs 73 during final operation of thecable 57 to actuate the latch, while the latter will be automaticallyreturned to and maintained in engaging position through the medium ofthe spring-plungers 52, which are guided in their movements through themedium-oi the projecting portions 54, working in the slots 55, as beforeexplained, it may also be mentioned that the guide-sections 48 serve inpractice to present an extended bean lug-surface tor the guides 40during move ment of the bar 4%? and also to effect proper alinement ofthe latter with the block 39 for insuring accurate engagement of thelatch 51 withthe keeper 50. Furthermore, it will be observed that underthe peculiar construction of the drum 8 the sections 19 and 20 thereofmay be readily disconnectedfor independent rotation in initially windingthe camedium of? lever 15,

-with the slidable member,

device with the carriage,

'tively connected with the drum-sections connected the cable 29 is firstwound upon the section 20, which is thereafter disconnected by removingthe bolt 23 to permit the cable 35 to be in turn wound in a reversedirection u on the drum-section 19, and, furthermore, t at through thisconstruction the cables. may be properly tensioned.

In Figs. 13 and 14 there is illustrated a modified form of load-gra lingdevice in which the relatively mova l; sections 44, carried and operatedby the levers 43, each comprise a cross'piece or bar 79 and teeth ortines 80, this form of grapple especially adapt-- ing the device for usein conveying and load-. ing hay or the like. 7 In other respects thedevice is identical in construction and operation with that abovedescribed.

From the foregoing it is, apparent that I produce a simple inex ensivedevice which in practice will admirab y perform its functions to theattainment of the ends in View, one in which the load-receiving deviceWill be properly moved with the carriage for conveying the load fromplace to lace, and one wherein the bucket-sections will be automaticallyoperati e both for receiving and; discharging the cad, it beingunderstood that ,minor changes in the details herein set forth may beresorted to without departing from the spirit of the invention.

Having thus described the invention, what I claim is 1. In a device ofthe class described, a loadi'eceiving device comprising a pair ofrelativel movable sections, a guide, a member 'slida ly mounted upon theguide and o eratively connected with the sections, a ead slidablyengaged with the guide, a movable latching member for connecting thehead autrack or'way, a and a hoisting-ca the load-receiving said cablebeing to release the carriage movable thereon ble operatively connectingadapted for actuating the latch slidable member from the head. r
